Android M：如何获取所有进程UID？

PackageManager pm = context.getPackageManager();
Activitymanager am = (Activitymanager) getSystemservice(Context.ACTIVITY_serviCE);
List<Activitymanager.RunningserviceInfo> runningservices = am.getRunningservices(Integer.max_value);
for (Activitymanager.RunningserviceInfo service : runningservices) {
    String appName;
    try {
        appName = pm.getApplicationInfo(service.process,0).loadLabel(pm).toString();
    } catch (PackageManager.NameNotFoundException E) {
        appName = null;
    }

    int uid = service.uid;

    long ulBytes = TrafficStats.getUidTxBytes(uid);
    long dlBytes = TrafficStats.getUidRxBytes(uid);
}

文档说明这不适用于生产.我也没有做太多测试.如果不符合您的要求,请发表评论.我能想到的另一件事就是在sHell中解析运行ps的输出.

在sHell中解析ps的输出,我们可以获得当前正在运行的应用程序.例：

PackageManager pm = context.getPackageManager();
// Get the output of running "ps" in a sHell.
// This uses libsuperuser: https://github.com/Chainfire/libsuperuser
// To add this to your project: compile 'eu.chainfire:libsuperuser:1.0.0.+'
List<String> stdout = SHell.SH.run("ps");
List<String> packages = new ArrayList<>();
for (String line : stdout) {
    // Get the process-name. it is the last column.
    String[] arr = line.split("\\s+");
    String processName = arr[arr.length - 1].split(":")[0];
    packages.add(processName);
}

// Get a list of all installed apps on the device.
List<ApplicationInfo> apps = pm.geTinstalledApplications(0);

// Remove apps which are not running.
for (Iterator<ApplicationInfo> it = apps.iterator(); it.hasNext(); ) {
    if (!packages.contains(it.next().packageName)) {
        it.remove();
    }
}

for (ApplicationInfo app : apps) {
    String appName = app.loadLabel(pm).toString();
    int uid = app.uid;
    long ulBytes = TrafficStats.getUidTxBytes(uid);
    long dlBytes = TrafficStats.getUidRxBytes(uid);
    /* do your stuff */
}
